The tv works about 10 min then the pic starts flickering.
There is adjustment to stop the flickering. But, you have to enter its service mode option do do this. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

SOURCE: My Polaroid TV model not listed, it's TLX-04240B
I got the 42" Polaroid HDTV from Walmart (on Black Friday) and was able to link it to my Tivo remote using the Mitsubishi setting and code 0001.
1. Tivo Central
2. Settings
3. Remote Control
4. Part 1 and then Part 3
I use it to Power On/Off and Volume control.

I have the same model, same problem. It doesn't need an inverter board. If its the same problem as mine was, it is a capacitor. I replaced the capacitor and it has worked fine since. It is a 220uf 450v capacitor on the right side of the top board. Its black and about 1.25" in diameter. It cost me $26.00, much better than the $250-$400 for someone to replace the whole board. Just check capacitor, if its domed or bubbled on top, it is bad. I have pics if you need [email protected]. Or more questions.

open the black plastic panel and the aluminum panel which has 3 screws each in the back of the tv.
look at bottom left corner of top board. to the right of the red led light,
there's these four white small switches. turn the bottom two switches to "on" and tv should be working.

Black screen canbe caused by bad T-CON board, main board, 24vdc power supply, backlight inverter board. Please my guide get more ideas on what to look for inside.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there is some troubleshooting you will have to do to find out the causes of the problem you are having.
